Method for an alarm event generator
摘要:
An alarm event generation method and apparatus for signaling an alarm (436, 1400) for a process control system (100). The process control system (100) monitors a production run using a computer system (108). The computer system (108) collects process data corresponding to the production run from operator workstations (104, 106) and stores the process data in a process data database (110). The process data includes a plurality of process parameter counts (430) each corresponding to a process parameter type (428). The process parameter counts (430) are polled from the computer system (108). Each process parameter count (430) has a corresponding manufacturing limit (434) to which it is compared. When a polled process parameter count (430) exceeds its corresponding manufacturing limit (434), an alarm (436, 1400) is signaled. While an alarm (436, 1400) is being signaled, the computer system (108) is prevented from collecting and storing process data.
